  • What emulation mode for an epson printer is best?

    - by deamon
    I'm looking for a color duplex printer for Ubuntu. My favourites are Epson B-310N and Brother HL 4050CDN. The latter should be work with linux, but I'd prefer the first one, because printing costs are cheaper. The epson printer has "Epson ESC/P Raster", "PCL3", and "Epson ESC/P2" emulation. Can I use the printer with one of those emulations under linux? Were there any restrictions (like unusable duplex)?

  • Class Design -- Multiple Calls from One Method or One Call from Multiple Methods?

    - by Andrew
    I've been working on some code recently that interfaces with a CMS we use and it's presented me with a question on class design that I think is applicable in a number of situations. Essentially, what I am doing is extracting information from the CMS and transforming this information into objects that I can use programatically for other purposes. This consists of two steps: Retrieve the data from the CMS (we have a DAL that I use, so this is essentially just specifying what data from the CMS I want--no connection logic or anything like that) Map the parsed data to my own [C#] objects There are basically two ways I can approach this: One call from multiple methods public void MainMethodWhereIDoStuff() { IEnumerable<MyObject> myObjects = GetMyObjects(); // Do other stuff with myObjects } private static IEnumerable<MyObject> GetMyObjects() { IEnumerable<CmsDataItem> cmsDataItems = GetCmsDataItems(); List<MyObject> mappedObjects = new List<MyObject>(); // do stuff to map the CmsDataItems to MyObjects return mappedObjects; } private static IEnumerable<CmsDataItem> GetCmsDataItems() { List<CmsDataItem> cmsDataItems = new List<CmsDataItem>(); // do stuff to get the CmsDataItems I want return cmsDataItems; } Multiple calls from one method public void MainMethodWhereIDoStuff() { IEnumerable<CmsDataItem> cmsDataItems = GetCmsDataItems(); IEnumerable<MyObject> myObjects = GetMyObjects(cmsDataItems); // do stuff with myObjects } private static IEnumerable<MyObject> GetMyObjects(IEnumerable<CmsDataItem> itemsToMap) { // ... } private static IEnumerable<CmsDataItem> GetCmsDataItems() { // ... } I am tempted to say that the latter is better than the former, as GetMyObjects does not depend on GetCmsDataItems, and it is explicit in the calling method the steps that are executed to retrieve the objects (I'm concerned that the first approach is kind of an object-oriented version of spaghetti code). On the other hand, the two helper methods are never going to be used outside of the class, so I'm not sure if it really matters whether one depends on the other. Furthermore, I like the fact that in the first approach the objects can be retrieved from one line-- most likely anyone working with the main method doesn't care how the objects are retrieved, they just need to retrieve the objects, and the "daisy chained" helper methods hide the exact steps needed to retrieve them (in practice, I actually have a few more methods but am still able to retrieve the object collection I want in one line). Is one of these methods right and the other wrong? Or is it simply a matter of preference or context dependent?

  • Working with Reporting Services Filters – Part 3: The TOP and BOTTOM Operators

    - by smisner
    Thus far in this series, I have described using the IN operator and the LIKE operator. Today, I’ll continue the series by reviewing the TOP and BOTTOM operators. Today, I happened to be working on an example of using the TOP N operator and was not successful on my first try because the behavior is just a bit different than we find when using an “equals” comparison as I described in my first post in this series. In my example, I wanted to display a list of the top 5 resellers in the United States for AdventureWorks, but I wanted it based on a filter. I started with a hard-coded filter like this: Expression Data Type Operator Value [ResellerSalesAmount] Float Top N 5 And received the following error: A filter value in the filter for tablix 'Tablix1' specifies a data type that is not supported by the 'TopN' operator. Verify that the data type for each filter value is Integer. Well, that puzzled me. Did I really have to convert ResellerSalesAmount to an integer to use the Top N operator? Just for kicks, I switched to the Top % operator like this: Expression Data Type Operator Value [ResellerSalesAmount] Float Top % 50 This time, I got exactly the results I expected – I had a total of 10 records in my dataset results, so 50% of that should yield 5 rows in my tablix. So thinking about the problem with Top N some  more, I switched the Value to an expression, like this: Expression Data Type Operator Value [ResellerSalesAmount] Float Top N =5 And it worked! So the value for Top N or Top % must reflect a number to plug into the calculation, such as Top 5 or Top 50%, and the expression is the basis for determining what’s in that group. In other words, Reporting Services will sort the rows by the expression – ResellerSalesAmount in this case – in descending order, and then filter out everything except the topmost rows based on the operator you specify. The curious thing is that, if you’re going to hard-code the value, you must enter the value for Top N with an equal sign in front of the integer, but you can omit the equal sign when entering a hard-coded value for Top %. This experience is why working with Reporting Services filters is not always intuitive! When you use a report parameter to set the value, you won’t have this problem. Just be sure that the data type of the report parameter is set to Integer. Jessica Moss has an example of using a Top N filter in a tablix which you can view here. Working with Bottom N and Bottom % works similarly. You just provide a number for N or for the percentage and Reporting Services works from the bottom up to determine which rows are kept and which are excluded.

  • signal processing libraries

    - by khinester
    Are there any open source libraries/projects which work in a similar way to http://www.tagattitude.fr/en/products/technology? I am trying to understand the process. At first I thought this could work like when you send a fax to a fax machine. It is basically using the mobile phone’s microphone as a captor and its audio channel as a transporter. Are there any libraries for generating the signal and then being able to decode it?

  • &ldquo;ASP.NET MVC 2 in Action&rdquo; Ebook is complete

    - by Brian Schroer
    I just got email notification that ASP.NET MVC2 in Action is complete. I had signed up for the Manning Early Access Program (MEAP), which allowed me to reserve a hardcopy of the book, a PDF of the completed chapters, and the PDF of the entire version 1 (ASP.NET MVC in Action) book all for $49.99. I’m working on my first MVC application, and it’s been a big help so far. Congratulations to Jeffrey Palermo, Ben Scheirman, Jimmy Bogard, Eric Hexter, and Matthew Hinze for completing what looks like a great book!

  • Macbook (non-pro, late 2010) Power Management Issues relating to Nvidia-Current drivers

    - by gbvitaobscura
    I have tried many potential solutions but to no avail! (this is going to be a long post) Essentially, when I first install ubuntu (I have tested 10.11-12.04 beta) I can change the brightness of the macbook backlight. One of the first things I usually do once my machine finishes installing is enter "sudo apt-get install nvidia-current" into the terminal to get my Nvidia graphics card set up. Before I install nvidia-current power management works flawlessly. After installing nvidia-current my graphics driver works mostly properly (more on that later). When I press F1 or F2 notify osd pops up and shows icon for the backlight along with a meter which changes according to how much I press F1 or F2, but the backlight does not change brightness at all. Two supplementary facts: when I am running off of battery power the backlight does not dim ever, also changing the backlight brightness through the terminal does not work (it recognizes the command but changes nothing). Things which did not work: 1. editing xorg.conf 2. python script/hack 3. editing grub Things which did work: 1. removing Nvidia-Current Final piece of information: Although my graphics card works in every way but Power Management it can not be found through System Settings/Details (Graphics Unknown) I'm using the NVIDIA GeForce 320M. the output of lspci is: 00:00.0 Host bridge: NVIDIA Corporation MCP89 HOST Bridge (rev a1) 00:00.1 RAM memory: NVIDIA Corporation MCP89 Memory Controller (rev a1) 00:01.0 RAM memory: NVIDIA Corporation Device 0d6d (rev a1) 00:01.1 RAM memory: NVIDIA Corporation Device 0d6e (rev a1) 00:01.2 RAM memory: NVIDIA Corporation Device 0d6f (rev a1) 00:01.3 RAM memory: NVIDIA Corporation Device 0d70 (rev a1) 00:02.0 RAM memory: NVIDIA Corporation Device 0d71 (rev a1) 00:02.1 RAM memory: NVIDIA Corporation Device 0d72 (rev a1) 00:03.0 ISA bridge: NVIDIA Corporation MCP89 LPC Bridge (rev a2) 00:03.1 RAM memory: NVIDIA Corporation MCP89 Memory Controller (rev a1) 00:03.2 SMBus: NVIDIA Corporation MCP89 SMBus (rev a1) 00:03.3 RAM memory: NVIDIA Corporation MCP89 Memory Controller (rev a1) 00:03.4 Co-processor: NVIDIA Corporation MCP89 Co-Processor (rev a1) 00:04.0 USB controller: NVIDIA Corporation MCP89 OHCI USB 1.1 Controller (rev a1) 00:04.1 USB controller: NVIDIA Corporation MCP89 EHCI USB 2.0 Controller (rev a2) 00:06.0 USB controller: NVIDIA Corporation MCP89 OHCI USB 1.1 Controller (rev a1) 00:06.1 USB controller: NVIDIA Corporation MCP89 EHCI USB 2.0 Controller (rev a2) 00:08.0 Audio device: NVIDIA Corporation MCP89 High Definition Audio (rev a2) 00:09.0 Ethernet controller: NVIDIA Corporation MCP89 Ethernet (rev a1) 00:0a.0 IDE interface: NVIDIA Corporation MCP89 SATA Controller (rev a2) 00:0b.0 RAM memory: NVIDIA Corporation Device 0d75 (rev a1) 00:15.0 PCI bridge: NVIDIA Corporation Device 0d9b (rev a1) 00:17.0 PCI bridge: NVIDIA Corporation MCP89 PCI Express Bridge (rev a1) 01:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01) 02:00.0 VGA compatible controller: NVIDIA Corporation Device 08a0 (rev a2) There is a very similar bug on Launchpad which I have posted below. https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/764195

  • SCOM, 90 Days In, II. Noise.

    - by merrillaldrich
    Once you get past the basic architecture of a SCOM implementation, and build the servers, and so on, the first real problem is … well, noise. Suddenly (depending on how you deploy) the system will reach out, like marching army ants or a some very clever cybernetic spider and find, and then proceed to yell at you about, every single problem on every server you didn’t know you had. That, of course, is the point. Still, a tool like this is not useful if it doesn’t surface the real problems from the...(read more)

  • Where would my different development rhythm be suitable for the work?

    - by DarenW
    Over the years I have worked on many projects, with some successful and a great benefit to the company, and some total failures with me getting fired or otherwise leaving. What is the difference? Naturally I prefer the former and wish to avoid the latter, so I'm pondering this issue. The key seems to be that my personal approach differs from the norm. I write code first, letting it be all spaghetti and chaos, using whatever tools "fit my hand" that I'm fluent in. I try to organize it, then give up and start over with a better design. I go through cycles, from thinking-design to coding-testing. This may seem to be the same as any other development process, Agile or whatever, cycling between design and coding, but there does seem to be a subtle difference: The methods (ideally) followed by most teams goes design, code; design, code; ... while I'm going code, design; code, design; (if that makes any sense.) Music analogy: some types of music have a strong downbeat while others have prominent syncopation. In practice, I just can't think in terms of UML, specifications and so on, but grok things only by attempting to code and debug and refactor ad-hoc. I need the grounding provided by coding in order to think constructively, then to offer any opinions, advice or solutions to the team and get real work done. In positions where I can initially hack up cowboy code without constraints of tool or language choices, I easily gain a "feel" for the data, requirements etc and eventually do good work. In formalized positions where paperwork and pure "design" comes first and only later any coding (even for small proof-of-concept projects), I am lost at sea and drown. Therefore, I'd like to know how to either 1) change my rhythm to match the more formalized methodology-oriented team ways of doing things, or 2) find positions at organizations where my sense of development rhythm is perfect for the work. It's probably unrealistic for a person to change their fundamental approach to things. So option 2) is preferred. So where I can I find such positions? How common is my approach and where is it seen as viable but different, and not dismissed as undisciplined or cowboy coder ways?

  • Bin packing part 6: Further improvements

    - by Hugo Kornelis
    In part 5 of my series on the bin packing problem, I presented a method that sits somewhere in between the true row-by-row iterative characteristics of the first three parts and the truly set-based approach of the fourth part. I did use iteration, but each pass through the loop would use a set-based statement to process a lot of rows at once. Since that statement is fairly complex, I am sure that a single execution of it is far from cheap – but the algorithm used is efficient enough that the entire...(read more)

  • Is there a difference between installing an application via Ubuntu Software Center or a terminal?

    - by gabriel
    I would like to ask a very basic question but I have never thought about it before. Well, when someone installs an application from terminal, he has to add the repository first, right? On the other side, when someone installs an application from the Ubuntu Software Center, is the repository then added automatically? I am asking those questions to figure out this: When I run update and then upgrade, will this application be upgraded or not? Is the result same in two options?

  • Make Firefox Show Google Results for Default Address Bar Searches

    - by The Geek
    Have you ever typed something incorrectly into the Firefox address bar, and then had it take you to a page you weren’t expecting? The reason is because Firefox uses Google’s “I’m Feeling Lucky” search, but you can change it. Scratching your head? Let’s take a quick run through what we’re talking about… Normally, if you typed in something like just “howtogeek” in the address bar, and then hit enter… you’ll be taken directly to the How-To Geek site. But how? Very simple! It’s the same place you would have been taken to if you typed “howtogeek” into Google, and then clicked the “I’m Feeling Lucky” button, which takes you to the first result. This is what Firefox does behind the scenes when you put something into the address bar that isn’t a URL. But what if you’d rather head to the search results page instead? Luckily, all you have to do is tweak an about:config parameter in Firefox. Just head into about:config in the address bar, and then filter for keyword.url like so: Double-click on the entry in the list, and then delete the &gfns=1 from the value. That’s the part of the URL that triggers Google to redirect to the first result. And now, the next time you type something into the address bar, either on purpose or because you typo’d it, you’ll be taken to the results page instead: About:Config tweaking is lots of fun.

  • Canonicalization of single, small pages like reviews or product categories

    - by Valorized
    In general I pretty much like the idea of canonicalization. And in most cases, Google explains possible procedures in a clear way. For example: If I have duplicates because of parameters (eg: &sort=desc) it's clear to use the canonical for the site, provided the within the head-tag. However I'm wondering how to handle "small - no to say thin content - sites". What's my definition of a small site? An Example: On one of my main sites, we use a directory based url-structure. Let's see: example.com/ (root) example.com/category-abc/ example.com/category-abc/produkt-xy/ Moreover we provide on page, that includes all products example.com/all-categories/ (lists all products the same way as in the categories) In case of reviews, we use a similar structure: example.com/reviews/product-xy/ shows all review for one certain product example.com/reviews/product-xy/abc-your-product-is-great/ shows one certain review example.com/reviews/ shows all reviews for all products (latest first) Let's make it even more complicated: On every product site, there are the latest 2 reviews at the end of the page. So you see, a lot of potential duplicates. Q1: Should I create canonicals for a: example.com/category-abc/ to example.com/all-categories/ b: example.com/reviews/product-xy/abc-your-product-is-great/ to example.com/reviews/product-xy/ or to example.com/review/ or none of them? Q2: Can I link the collection of categories (all-categories/) and collection of all reviews (reviews/ and reviews/product-xy/) to the single category respectively to the single review. Example: example.com/reviews/ includes - let's say - 100 reviews. Can I somehow use a markup that tells search engines: "Hey, wait, you are now looking at a collection of 100 reviews - do not index this collection, you should rather prefer indexing every single review as a single page!". In HTML it might be something like that (which - of course - does not work, it's only to show you what I mean): <div class="review" rel="canonical" href="http://example.com/reviews/product-xz/abc-your-product-is-great/"> HERE GOES THE REVIEW</div> Reason: I don't think it is a great user experience if the user searches for "your product is great" and lands on example.com/reviews/ instead of example.com/reviews/product-xy/abc-your-product-is-great/. On the first site, he will have to search and might stop because of frustration. The second result, however, might lead to a conversion. The same applies for categories. If the user is searching for category-Z, he might land on the all-categories page and he has to scroll down to the (last) category, to find what he searched for (Z). So what's best practice? What should I do?

  • A Bad Day at Work

    - by TehGrumpyCoder
    There's lots of ways of having a bad day at work... I suppose for many people, just being *at* work makes it a bad day, but I happen to be one of those people that found a way to do something I like for a living. I've always said "if you're not having fun, what's the point?" ... on the latest Zune podcast, they were interviewing someone from the WP7 team and he said they're mantra is "It's not done until it's fun" ... I like that too. But, even when you're doing what you like for a living, it can get tedious. There were times that I didn't look forward to going out and playing guitar on a Friday or Saturday night, and some nights I was looking at my watch just waiting for it to be over. Well, that was today... like Steve Martin in "The Jerk" ... the first hour was like a regular hour, but then the rest of the morning was like a day, and the afternoon has been like a week. I've got a list of stuff I need to get into my head, and it's tough when the highest technology you have during 9 hours of your day is .NET 2.0 and you can only run what IT installed. I get wrapped around the power take-off reading something and dearly want to write some code to try, but with the state of technology here, it's like trying to teach jazz chords to someone that showed up for their lesson with that stupid plastic guitar from Guitar Hero. I tried to watch a training video... downloaded it zipped so maybe it wouldn't be noticed like it might if I streamed it. Then nothing on this machine would play the video... dang! Well, if someone doesn't take me out on the drive tonight or back in tomorrow, maybe it'll be a better day... or maybe I'll d/l a bunch of training videos in a different format, or bring in a decent viewer, or download them to my Zune maybe... that would work. I suppose at age 61 there are worse things than feeling stifled... for instance, so far I've lived 2 years longer than my father... but at the same time, he's the one that pointed out that in my first letter home from Boot Camp "He's complaining, he's fine"... guess he had my number :) I think he'd appreciate "Teh Grumpy Coder"

  • Mixed Solaris 10 and 11 versions in logical domains on the same server

    - by jsavit
    One question that comes up frequently is whether you can mix Solaris 10 and Solaris 11 in different logical domains under Oracle VM Server for SPARC. The answer is yes depending only on the system software requirements for the underlying hardware platform. Different versions of Solaris 10 and 11 can exist side-by-side on the same server and can act as control, service, I/O or guest domains subject only to the minimum software levels documented in the System Requirements section of the Oracle VM Server for SPARC Release Notes. Here's an example just taken from a running system. First, here's the control domain, which is running Solaris 10. I've highlighted a guest running Solaris 11. # uname -a SunOS atl-sewr-24 5.10 Generic_147440-01 sun4v sparc SUNW,SPARC-Enterprise-T5220 # ldm -V Logical Domains Manager (v 2.1) Hypervisor control protocol v 1.7 Using Hypervisor MD v 1.3 System PROM: Hypervisor v. 1.10.0 @(#)Hypervisor 1.10.0 2011/04/27 16:19\015 # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- SP 16 4G 1.6% 120d 17h atl-sewr-pool-148 active -n---- 5001 8 2G 0.1% 119d 21h atl-sewr-pool-152 active -n---- 5000 8 4G 0.2% 112d 19h atl-sewr-pool-154 active -n---- 5002 8 2G 0.1% 120d 15h atl-sewr-pool-155 active -n---- 5003 16 2G 0.0% 26d 14h 30m This system is running Oracle VM Server 2.1 with a Solaris 10 control domain. Hmm, I should update this machine to 2.2 when I get a few free moments. Upgrading is very straightforward. Here's a display logging into the highlighted guest: Last login: Mon May 21 10:18:16 2012 from dhcp-adc-twvpn- Oracle Corporation SunOS 5.11 11.0 November 2011 sewr@atl-sewr-pool-152:~$ uname -a SunOS atl-sewr-pool-152 5.11 11.0 sun4v sparc SUNW,SPARC-Enterprise-T5220 sewr@atl-sewr-pool-152:~$ cat /etc/release Oracle Solaris 11 11/11 SPARC Copyright (c) 1983, 2011, Oracle and/or its affiliates. All rights reserved. Assembled 18 October 2011 sewr@atl-sewr-pool-152:~$ sudo virtinfo -ct Password: Domain role: LDoms guest Control domain: atl-sewr-24 sewr@atl-sewr-pool-152:~$ That's running the GA version of Solaris 11, so I probably should update that some time too. Note the use of the virtinfo -ct command that lets the guest get information about the hosting environment. Summary You can mix and match versions of Solaris in logical domains. All the different combinations work: Solaris 10 and/or Solaris 11 control and service domains with Solaris 10 and/or Solaris 11 guests. Mixing different guest OS levels on the same server is one of the traditional reasons for using virtual machines in the first place since virtual machines were invented some 40 years ago, used to run production and test systems in parallel while upgrading OS levels. This can easily be done with Oracle VM Server for SPARC (Logical Domains).
